Definitions
- the present disclosure relates to an ink refill container configured to refill ink to an ink tank provided to accumulate therein ink that is to be supplied to a recording device, as well as to an ink refill system configured to include such an ink refill container.
- An ink tank configured to accumulate ink therein is generally connected with a recording device that performs recording by ejecting ink onto a medium, in such a state that ink is suppliable from the ink tank.
- a recording device that performs recording by ejecting ink onto a medium, in such a state that ink is suppliable from the ink tank.
- the ink tank is externally refilled with ink by using an ink refill container (as described in, for example, Patent Literature 1).
- an object of the present disclosure is to provide an ink refill container configured to appropriately refill an ink tank with ink and an ink refill system including such an ink refill container.
- An ink refill container configured to refill ink into an ink tank that has an ink inlet flow path portion and an ink chamber arranged to communicate with the ink inlet flow path portion.
- the ink refill container comprises a container main body provided to include an ink chamber configured to contain therein ink, which is to be refilled to the ink tank; an ink outlet forming portion provided at an edge of the container main body to include an ink outlet configured to allow the ink to flow out from the ink chamber; a valve provided in the ink outlet forming portion and configured to seal the ink outlet in an openable and closable manner; and a positioning structure configured to abut on part of the ink tank and position the valve relative to the ink tank when the valve is opened.
- the positioning structure has a positioning surface that is located on an opposite side to a container main body side where the container main body is located, across the valve and that is extended in a direction intersecting with a center axis of the ink outlet.
- the positioning surface abuts on the part of the ink tank, when the ink inlet flow path portion of the ink tank is inserted into the ink outlet to open the valve.
- the positioning surface when the ink refill container is moved toward the ink tank and the ink inlet flow path portion of the ink tank is inserted into the ink outlet to open the valve, the positioning surface is moved toward the ink tank, prior to the valve.
- a configuration provided to guide the move of the positioning surface in a direction of insertion of the ink inlet flow path portion into the ink outlet enables the ink inlet flow path portion to be readily guided relative to the valve.
- the positioning surface abuts on part of the ink tank in the process of ink refill to the ink tank, the attitude of the ink refill container is stabilized in the direction intersecting with the center axis of the ink outlet. This facilitates the ink refill and enables the ink tank to be appropriately refilled with ink.
- the positioning surface may be located on the opposite side to the container main body side across the ink outlet in a direction along the center axis of the ink outlet.
- the positioning surface approaches the ink tank, prior to the ink outlet.
- This configuration readily prevents the ink outlet from colliding with other members when the ink refill container approaches the ink tank. This accordingly readily prevents damage of the ink outlet and adhesion of ink to other members.
- the positioning surface may be formed at a leading end of a tubular portion that forms the ink outlet to be open outward at an edge of the ink outlet forming portion.
- the positioning surface is formed on the tubular portion that, along with the ink outlet, forms the ink outlet forming portion. This simplifies the configuration, compared with formation of the positioning surface by a projection or the like provided at a different position from the ink outlet.
- the ink refill container configured to refill ink into an ink tank that has an ink inlet flow path portion and an ink chamber arranged to communicate with the ink inlet flow path portion.
- the ink refill container comprises a container main body provided to include an ink chamber configured to contain therein ink, which is to be refilled to the ink tank; an ink outlet forming portion provided at an edge of the container main body to include an ink outlet configured to allow the ink to flow out from the ink chamber; a valve provided in the ink outlet forming portion and configured to seal the ink outlet in an openable and closable manner; and a positioning structure configured to abut on part of the ink tank and position the valve relative to the ink tank when the valve is opened.
- the ink outlet is formed in a tubular portion that is part of the ink outlet forming portion.
- the positioning structure includes a positioning surface that is provided to be opposed to an outer face of the tubular body across a clearance and that is extended in a direction intersecting with a center axis of the ink outlet. The positioning surface abuts on the part of the ink tank, when the ink inlet flow path portion of the ink tank is inserted into the ink outlet to open the valve.
- the positioning surface extended in the direction intersecting with the center axis of the ink outlet abuts on part of the ink tank.
- This configuration enables the ink tank in the stable state to be appropriately refilled with ink.
- This configuration also causes ink adhering to the ink outlet or to the positioning surface to be drawn into the clearance and thereby reduces the possibility of ink dripping and external contamination.
- an area of the positioning surface abutting on the part of the ink tank on a side farther from the ink outlet in the direction intersecting with the center axis of the ink outlet may be larger than an area of the positioning surface abutting on the part of the ink tank on a side closer to the ink outlet.
- This configuration enhances the stability of the attitude of the ink outlet in the ink refill state where the ink inlet flow path portion is inserted into the ink outlet to open the valve.
- the ink refill container configured to refill ink into an ink tank that has an ink inlet flow path portion and an ink chamber arranged to communicate with the ink inlet flow path portion.
- the ink refill container comprises a container main body provided to include an ink chamber configured to contain therein ink, which is to be refilled to the ink tank; an ink outlet forming portion provided at an edge of the container main body to include an ink outlet configured to allow the ink to flow out from the ink chamber; a valve provided in the ink outlet forming portion and configured to seal the ink outlet in an openable and closable manner; and a positioning structure configured to abut on part of the ink tank and position the valve relative to the ink tank when the valve is opened.
- the positioning structure includes a positioning surface that is inclined or curved in a direction intersecting with a center axis of the ink outlet.
- the positioning surface abuts on the part of the ink tank, when the ink inlet flow path portion of the ink tank is inserted into the ink outlet to open the valve.
- This configuration positions the ink refill container in both a direction along the center axis of the ink outlet and a direction orthogonal to the center axis in the process of ink refill from the ink refill container to the ink tank and thereby ensures appropriate ink refill.
- the positioning surface may be inclined or curved in a direction gradually farther away from the center axis, with respect to a direction from the ink outlet toward the container main body.
- This configuration enables the ink refill container to be gradually guided along the inclined or curved positioning surface when the ink inlet flow path portion is inserted into and pulled out from the ink outlet.
- the positioning structure may be provided in a region exposed outside in at least one of the ink outlet forming portion and the container main body.
- This configuration causes the positioning structure to be readily visible from outside when the ink inlet flow path portion of the ink tank is inserted into the ink outlet of the ink refill container.
- the positioning structure is provided in the region exposed outside in the container main body, the container main body that contains ink therein is positioned. This means positioning of the heavy portion and thereby stabilizes the attitude of ink refill.
- the ink refill container configured to refill ink into an ink tank that has an ink inlet flow path portion and an ink chamber arranged to communicate with the ink inlet flow path portion.
- the ink refill container comprises a container main body provided to include an ink chamber configured to contain therein ink, which is to be refilled to the ink tank; an ink outlet forming portion provided at an edge of the container main body to include an ink outlet configured to allow the ink to flow out from the ink chamber; a valve provided in the ink outlet forming portion and configured to seal the ink outlet in an openable and closable manner; and a positioning structure configured to abut on part of the ink tank and position the valve relative to the ink tank when the valve is opened.
- the positioning structure is provided inside of the ink outlet.
- This configuration protects the positioning structure inside of the ink outlet and is thus unlike to damage the positioning structure, compared with a configuration that the positioning structure is provided outside of the ink outlet.
- the positioning structure is placed near to the valve inside of the ink outlet. This configuration enables the valve to be positioned relative to the ink tank with high accuracy. Furthermore, even when ink adheres to the positioning structure located inside of the ink outlet, this configuration reduces the possibility that ink adheres to outside of the ink refill container.
- the ink refill container in the process of ink refill from the ink refill container to the ink tank, is appropriately positioned relative to the various ink tanks by means of the auxiliary positioning member.
- the auxiliary positioning member may be formed from an ink absorber that is configured to absorb ink.
- the ink absorber relieves the impact when the positioning structure of the ink refill container abuts on part of the ink tank. Absorption of ink by the ink absorber reduces dripping or spatter of ink when the ink refill container is dismounted.
- the ink refill container configured to refill ink into an ink tank that has an ink inlet flow path portion and an ink chamber arranged to communicate with the ink inlet flow path portion.
- the ink refill container comprises a container main body provided to include an ink chamber configured to contain therein ink, which is to be refilled to the ink tank; an ink outlet forming portion provided at an edge of the container main body to include an ink outlet configured to allow the ink to flow out from the ink chamber; a valve provided in the ink outlet forming portion and configured to seal the ink outlet in an openable and closable manner; and a positioning structure configured to abut on part of the ink tank and position the valve relative to the ink tank when the valve is opened.
- the valve configured to open and close the ink outlet is positioned relative to the ink tank. This facilitates the ink refill and enables the ink tank to be appropriately refilled with ink.
- the following describes a first embodiment of an ink refill system including ink tanks and ink refill containers in a recording device with reference to drawings.

- the user In the process of ink refill to the ink tank 41, the user first rotates the open/close door 35 of the housing 22 forward around the rotating shaft 36 as the center from the closed state shown in Fig. 1 to open the open/close door 35.
- the upper face 58 of the ink refill adapter 47 with the ink inlets 53 for the ink tanks 41 to 45 in the ink supply unit 40 is accordingly exposed outside of the housing 22. This allows the user to connect the ink outlet 65 of the ink refill container 63 downward with a desired ink inlet 53.
- the user turns the ink refill container 63 containing black ink used for ink refill upside down and holds the ink outlet 65 to be located above the through hole 60 on the rightmost side in the ink refill adapter 47.
- the user compares the color of the container additional portion 67 (second portion) of the ink refill container 63 held in the hand with the color of the peripheral portion of the upper opening edge of the through hole 60 (first portion) provided with the ink inlet 53 of the ink tank 41 as the object of ink refill.
- the respective colors are the same color (black in this case)
- the user confirms that the ink refill container 63 suitable for the current ink refill is held in the hand and shifts to a subsequent operation for ink refill.
- the ink refill container 63 is then lowered from the state shown in Fig. 12 and Fig. 13 , so that the projections 71 of the ink refill container 63 are inserted into the recesses 61 of the ink refill adapter 47 integrated with the ink tank 41.
- the insertion of the projections 71 into the recesses 61 assures alignment of the center axis 85 of the ink outlet 65 with the center axis of the ink inlet 53.
- the recesses 61 are arranged to be symmetric with respect to the needle 56 at the center of the ink inlet 53, so that each projection 71 is insertable into either of the recesses 61.
- the projections 71 are only slightly inserted into the recesses 61.
- the leading end of the needle 56 located at the center of the ink inlet 53 is inserted in the opening of the ink outlet 65 that is slightly protruded from the leading end of the projections 71 but does not reach the valve 74 that is located in the depth of the ink outlet 65.
- a distance L2 between the leading ends of the projections 71 and the valve 74 in the ink outlet 65 is greater than a distance L1 between the upper face 58 of the ink refill adapter 47 where the opening edges of the recesses 61 are located and the upper edge of the first concavo-convex elements 62 in the recesses 61 as shown in Fig. 13 .
- the leading end of the needle 56 spreads the slits 75 of the valve 74 upward (i.e., inward of the ink outlet 65), so as to open the valve 74.

- one flow path out of the two flow paths 54 and 55 formed in the needle 56 in the ink inlet 53 serves as an ink flow path which ink flows in, while the other flow path serves as an air flow path which the air flows in.
- one of the two flow paths 54 and 55 serving as the ink flow path is changed according to the direction of the inclination.
- the user can recognize that the ink refill container 63 which the user tries to insert is a wrong ink refill container 63 containing a different color ink other than black at this moment.
- a configuration that the upper edge of the first concavo-convex elements 62 and the opening edge of the recesses 61 are located at the same height rejects not only engagement of the second concavo-convex elements 72 with the first concavo-convex elements 62 but insertion of the projections 71 into the recesses 61.
- the height of the first concavo-convex elements 62 is lower than the opening edge of the recesses 61. This causes the projections 71 to be readily guided toward the bottom face in the depth direction of the recesses 61 in the process of insertion into the recesses 61 and thereby suppresses an unnecessarily long time from being taken.
- the positioning structure 73 in the planar shape of the ink refill container 63 that serves as the positioning surface extended in the direction orthogonal to (intersecting with) the center axis 85 of the ink outlet 65 abuts on the upper face 58 of the ink refill adapter 47, so that the valve 74 is opened in the state of being positioned in the direction of the center axis of the ink outlet 65 relative to the needle 56 of the ink tank 41 (42 to 45).

- Ink is likely to be accumulated on the bottom face where the base end of the needle 56 in the ink inlet 53 is located. This configuration, however, prevents the accumulated ink from adhering to the leading end of the ink outlet 65 to stain the ink refill container 63.
- the ink refill may be performed again to further add ink to the upper limit mark 51 by using the same black ink refill container 63.
- the above description on the ink refill operation with regard to the black ink tank 41 is similarly applicable to the other color ink tanks 42 to 45.

- the lead-out flow path 193 communicates with inside of the ink tank 131 via a flow path 53A and a flow path 53B in the connecting tube 149.
- This configuration enables ink contained in the ink refill container 162 to be injected into the ink tank 131 via the connecting tube 149.
- inside of the connecting tube 149 is parted into the two flow paths 53A and 53B.
- This configuration causes the ink contained in the ink refill container 162 to flow through one of the flow paths 53A and 53B into the ink tank 131, while causing the atmosphere in the ink tank 131 to flow through the other of the flow paths 53A and 53B into the ink refill container 162.
